SPECIFICATION forming part of Letters Patent No. 512,435, dated January9, 1894.

Application filed April 14, 1893. $erial No. 470,546. (No model.)

T0 at whom it may concern.-

Be it 'known that I, IRAD L. GARSIDE, of Paterson, New Jersey, haveinvented a new and useful Improvement in Door-Bells and SimilarApparatus, of which the following is a description, referring to theaccompanying drawings, which form a part of this specification.

My invention relates to the class of bells inwhich rapid vibration ofthe hammer or hammers against a gong is produced by mechanical devices,the sound produced being 1soinlllilar to that of the usual vibratingelectric My invention is adapted to be used for door bells, bicyclebells, alarm bells, and many other purposes, it being only necessary tosuitably arrange and connect the bell either directly or by well-knownbell-hangers connections, so that the bell may be operated directly orfrom a distance, according to the requirements.

Under my invention, I preferably operate the bell by means of a pressbutton closely resembling the usual electrical rosette pressbuttonswitch. The energy of the pressure is mechanically transmitted to thebell-l1ammers, causing them to rapidly strike the bell, giving a soundsimilar to the usual electric bells. When the press button is released,the motion of the hammers is reversed under the action of a spring, andthe bell rings while the parts are being restored under the action ofthe spring, to their normal position.

My invention is embodied more particularly in the arrangement of thepress button, the mechanical train for giving motion to the hammers orstrikers, and the arrangement and mounting of the hammers or strikersthemselves. My-purpose is to produce a bell closely resembling anelectric bell, and giving a maximum number of strokes for minimumefiort. In addition to this, I am able by my invention to produce asimple, durable, reliable, and inexpensive bell, not easily gotten outof order, and capable of being readily repaired.

To these and certain other incidental ends and purposes, my invention isembodied in the apparatus and its several parts, constructed, arranged,combined, and used substantially in the manner hereinafter described,illustrated and claimed.

In the accompanying drawings, Figure 1 is an elevation showing oneembodiment of my bell mounted upon a door or partition, the bell, door,and rosette being in cross-section to expose the working parts. Fig. 2is a plan view of the bell with the gong removed, showing the mechanicaltrain and the arrangement and mounting of my hammers or strikers. Fig. 3is a detail perspective view of my bell crank lever, for transmittingthe pressure from the press button to the train of gears. Fig. 4 is adetail perspective view showing the sector gear which receives motionfrom the bell crank, and Figs. 5 and 6 are detail perspective views 01":the hammer or striker support or plate, and one hammer or striker.

Throughout the figures, like letters of reference indicate like parts.

In the drawings l have selected for illustration one of the simplest andpreferred forms of my bell, as arranged upon a door or partition A, thebell or gong K with its actuating mechanism being upon one side, and apush button 0 mounted in a rosette B being upon the other side arrangedto transmit pressure from the push button by the pin D directly to thebell mechanism. The rosette and push button are designed to resembleclosely the usual electric push-button switches. The push-button is heldin its normal position as shown in the figure, by means of the bellcrank E, transmitting the pressure of the return spring P as willhereinafter more fully appear.

M indicates the base or frame of the bell adapted to be secured to thedoor or partition A, as shown, and provided with the yoke, givingbearings for the arbors of the gears, and carrying the screw stud L bymeans of which the gon g K issupported. The gong is slipped upon thescrew stud L against a shoulder, as shown, and a nut T screwed down,holding it in place, as in the figure. The hammers or strikers J,loosely supported in the supports or plate I, mounted upon the shaft H,are located in such a position that the rotation of the shaft ll causesthem to fly out and strike the bell in rapid succession. The support orplate I, best shown in Fig. 5, is struck up from a Hat blank, as clearlyseen; the parts Q and B being turned up, as shown, and provided withperforations or slots, fitting the strikers or hammers J, Fig. 6. Thestrikers J are also struck up or stamped in the form shown, with therearward-extending pin or guide j turned up at right-angles at the end.The hammers or strikers J are mounted in the support or plate I byinserting the guide pin j through the guide R and then pushing thehammer forward through the guide Q into the position shown in Figs. 1and 2. The shaft or arbor II is then inserted through the central holein the plate I, and soldered in place. This interferes with thewithdrawal of the hammers, as they cannot be pushed back, after thearbor is in place, far enough to withdraw the hammers from the guides Q.It is to this simple and very effective construction of hammers andhammer plate, that many of the great advantages of my invention are due,for, clearly, the hammers and their supports may be manufactured at amost trifling cost, and in their operation, they are more simple,direct-acting, and reliable, than any similar arrangement with which Iam acquainted. WVhen the shaft is rotated, the centrifugal force throwsthe hammers outward into contact with the bell, and after striking, theyrebound and are thrown back to pass clear of the bell until they canrevolve into position to strike. To this sliding motion of the hammers Iattach considerable importance, because not only is it more simple andmore easily formed than the pivotal connections heretofore used, but Ifind that either because the shock of impact is less, or from some othercause, less power is required to give a certain number of blows, thanwith other forms.

The shaft H is provided with a pinion w, driven by the larger gear WVmounted upon a shaft W with the small pinion G. This small pinion Greceives its motion from the sector gear F mounted on the shaft V. Thisshaft is surrounded by the helical spring P secured to the base or frameat one end and to the sector gear F at its other end, as shown. Thissector gear is provided with the perforation or slot 0 through whichextends one end E of the bell crank lever E. The bell crank lever ispivoted at U transversely to the shaft V, so that, as it rocks, the endE gives or recelves motion to or from the sector F. The otherarm of thebell crankE is provided with the rounded bearing face or end E" whichpresses against the end of the pin D secured to the push-button C. ThespringPtends to turn the sector gear F in direction to cause the bellcrank E to drive the push-button O outward, as shown in Fig. 1. Whenpressure is applied to the push-button, the pin D turns or rocks thebell crank E, rotating the sector gear G against the action of thespring and transmitting the motion with greatlyincreased speed, throughthe gearing, to the hammerplate I. With the gearing shown, one thrust ofthe push-button G is designed to give about seventy-five or one hundredstrokes of the bell. When the push button is released, the recoil of thespring Pgives the same number in the reverse direction. Of course thegearing may be modified to give a greater or less number. Theintermediate shaft with the gears W and G, may be dispensed with, andmore powerful and direct action with a less number of strokes, obtained.So, also, some parts of the invention may be used without others, andvarious modifications may be made in the forms, proportions and detailsof the parts, to adapt the bell for a table call bell, or for use onbicycles, and in similar employments.

I have now set forth one embodiment of my invention, and the way inwhich it may be employed I have purposely omitted all description ofwiring and bell-hangers connections by which the bell may be operatedfrom a distance; and have omitted the enu meration of many modificationsthat may be made without departing from the principles of myinvention,because, to set forth such constructions and details wouldobscure rather than make clear the more essential features of my device.

Having, however, clearly explained my invention in one form, I claim,desiring to se cure by these Letters Patent all such changes andmodifications as may be made by more skill in the art, the following:

1. In combination in a bell, an actuating push rod or pin D, a bellcrank E, and gearing for actuating the hammers or strikers, the saidbell crank E projecting through a perforation contained in the saidgearing, for driving it, substantially as and for the purposes setforth.

2. In combination in a bell, an actuating push rod or pin D, abell crankE, sector gear F containing a perforation 0 through which the said bellcrank projects, and a bell ringing mechanism operated by the said gearF, substantially as and for the purposes set forth.

3. The improved bell hammer or striker consisting of a support or plateI having one or more pairs of perforated or slotted guides Q R, and oneor more hammers or strikers mounted in the said guides of the saidplate, substantially as and for the purposes set forth.

4. The improved bell hammer or striker consisting of a support or plateI formed of a blank having turned-up portions Q R forming guides, andone or more hammers or strikers J therefor, provided with guide pins jhaving heads or turned-up ends restricting the outward movement of thehammers or strik- 512,435 v as ers', and an arbor 0r shaft H restrictingthe inward movement'of such hammers 0r strikers, substantially as andfor the purposes set forth.

5. The improved hammer or striker support I for bells formed of aplateor blank having turned up or struck-up portions slotted 0rperforated to form guides for the hammers or strikers, substantially asand for the purposes set forth.
